The solution is an example of solving a globally constrained problem using the divide-and-conquer technique, rather than the usual backtracking algorithm. The former is much faster in both sequential and parallel environments.doi:10.1016/0743-7315(89)90011-7Bruce Abramson...

Edsger Dijkstraused this problem in 1972 to illustrate the power of what he calledstructured programming. He published a highly detailed description of the development of adepth-firstbacktracking algorithm.2 Below is one solution for 8 or N queen puzzle using C language description,you can define ...
